Abstract

The heat balance integral method (HBIM), a front tracking method, has been previously applied successfully to problems involving plane and cylindrical geometries. In this paper the method is applied to spherical solidification. For validation purposes a numerical scheme based on the enthalpy method is also used. This method provides a means of tracking the position of the phase front with very little additional effort. The results show that the two methods compare well over a wide range of Stefan number.
